如何猜测生词（二）
③通过构词法猜词：在阅读文章时，我们总会遇上一些新词汇，有时很难根据上下文来推断其词义，而它们对文章的理解又有着举足轻重的作用，此时，如掌握了一些常用的词根、前缀、后缀等语法知识，这些问题便解决了。
④利用解释线索：有时我们能从生词的前后找到解释性文字。例如：On Christmas Eve—the night before Christmas daychildren all over Britain put a stocking at the end of their beds before they go to sleep.从破折号后面给出的解释可知“Christmas Eve” 是“圣诞节前夕” 。
⑤利用常识线索：有时一句话中尽管有生词，但我们可以根据某些基本常识去判断生词的意思。例如：Thomas Edison was a great American inventor. 根据常识判断“爱迪生” 是“发明家” （inventor）。

Passage 2
It is wellknow that English go out with an umbrella or a raincoat. Why？ The weather in Britain often changes quickly. It is not very common for the same kind of weather to stay long.①
Spring can be rainy or windy， but the weather is getting warmer and you can expect more sunny days. In fact there can be as much sunshine in spring as in summer. May is very often a lovely warm month in many parts of Britain. Parks， gardens and the countries are very green and full of flowers， so people can have a lot of things to do and see out of doors at this time of year.
Summer is the most popular time for visitors to go to the seaside and other places. The weather can be sunny and pleased. People usually have outdoor activities such as swimming and outing.
Autumn is a beautiful season， with trees in the woods and parks changing color. It is bumper （极大的） crop season of agricultural plants （农作物）. Autumn is still pleasant to be outside although the weather changes， too.②
In winter， it is getting colder. It might snow， especially on high ground and in the north. There are also storms （暴风雪） and high winds in the season.
January and February are the coldest months of the year， while the warmest are often July and August.
